BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention is directed generally to a method and system forsignal distribution and, more particularly, to an intelligent devicesystem and method for distribution of digital signals onto, and off of,a wideband signal distribution system.

2. Description of the Background

The workplace currently has telephone and data networks that allow forboth verbal communication and the exchange of information via words,pictures, and numbers. However, bringing the communication media oftelevision and video into the networked environment has presented newdifficulties. In particular, digital TV/video applications clog datanetworks, even with the use of available compression techniques, such asMPEG2. Analog RF distribution may require special cables andinfrastructure, or more complex technologies.

However, using a wideband signal distribution system, such as thatdisclosed in U.S. Pat. No. 5,901,340, TV and video, both digital andanalog, can now move between locations in a building or campus just aseasily, and using the same infrastructure, as voice and data. In fact,TV, video, PBX, IP, and other data types can be moved over the sametypes of wires, including some unused wires, that already exist in mostnetworked environments. For example, telephone and computer networks inmost buildings are wired to meet a single, internationally acceptedwiring standard using, such as Category 5 or better twisted pair wiring.Residential buildings are often wired to similar standards. In typicalapplications using analog video over standard wiring systems, the analogvideo arrives uncompressed, and the user sees it on a TV, PC or monitorin enhanced quality. This method of live-feed video transfer allows forthe removal of space consuming files and applications currently storedon a network.

However, using solely uncompressed analog transfer of information doesnot fully solve the need to download to individual users largequantities of digitized images (video, film, animation, simulations,etc.), and to thereby allow those digital images to be displayed withthe enhanced quality such digital images can offer. At times, criticalneeds for digital video, such as analyzing or editing images, arise thatcannot be handled by purely analog signal transfer. Additionally, wheredigital video information is sent over a baseband LAN, i.e. Ethernet,the performance of the system is often severely degraded as the digitalvideo is sent simultaneously to an increasingly greater number ofreceivers.

Furthermore, digital IP data has historically been transferred usingdigital data networks, i.e. has been transferred in a digitized formatover a network capable of transporting a purely digitized format.However, analog carrier networks, using twisted pair wiring, for exampleCategory 5 Cable or better, have the capability to transport digitalvideo, IP voice/data/video, as well as analog video, efficiently andcost effectively. This capability is not presently used due to the lackof a method to get such signals onto and off of such a carrier network.

It would be desirable to transport the digitized data on an analogcarrier, such as over the existing Category 5 or better cable, in aformat that would allow for greater amounts of data to be carried at onetime, such as by modulated RF. In addition, it may be desirable in thefuture to use media other than Category 5 or better cabling to wirebuildings. Alternative wiring media, or wireless media, could allow thenetwork to overcome bandwidth problems by providing significantlyimproved data transfer speeds and increased bandwidth. Such alternativemedia could allow the network to overcome the aforementioned problems intransferring data and video over networks in a digitized format.However, such alternative wiring media will also require the completerewiring of many networks on, perhaps, a building environment level, asall Category 5 or better cable will need to be replaced with the newmedia, in order to provide the enhanced capabilities of the alternativemedia system to all users.

Therefore, the need exists for a network of intelligent devices thatenables digital video, IP voice/data/video, to be modulated anddemodulated onto and off of, preferably, a wideband signal distributionsystem or component equivalent, such as an analog carrier system. Suchan intelligent device network would facilitate the use of, for example,the existing global EIA/TIA 568 standard wiring infrastructure in aparticular environment, such as an office building, to significantlyincrease the information throughput. Additionally, such an intelligentdevice network would eliminate the need to rewire a building or addexpensive optoelectronic equipment to increase throughput on theexisting infrastructure.

BRIEF SUMMARY OF THE INVENTION

The present invention is directed to a signal distribution system,including at least one intelligent device system, for putting digitalsignals onto, and taking digital signals off of, a wideband signaldistribution system. A wideband signal distribution system typicallyincludes a distribution unit having a plurality of inputs and outputs,and a series of cables, such as twisted pair cable, running between aplurality of outlets and the inputs and outputs of the distributionunit.

An intelligent device system may be, for example, a local RFreceiver/baseband out intelligent device system. The local RFreceiver/baseband out intelligent device system includes at least oneaddressable device having at least one input and at least one output, aBUD that receives a signal, which signal includes at least a digitalsignal portion, from the output of an intelligent device, and theintelligent device that receives, from the BUD, a modulated RF signalcarrying at least a digital signal portion thereon. The intelligentdevice splits the IP signal portion from a non-IP signal portion, andremoves the modulated RF carrier from the digital signal portion beforesending the digital signal portion to the input of at least one of theaddressable devices, and sending the non-IP signal portion to a standardoutlet. The intelligent device may include at least one DSP thatcontrols the demodulation and filtering. Additionally, the local RFreceiver/baseband out intelligent device may include wirelesscapability.

An intelligent device system may also be, for example, an intelligentdevice system for remote sending. The intelligent device system forremote sending preferably includes at least one incoming signalgenerator, wherein an incoming signal generated includes at least a IPsignal portion, a BUD that receives the incoming signal at at least oneinput port, and that includes at least one output port, and a remotesend intelligent device that generates a modulated RF signal carryingthe IP signal portion thereon. The remote send intelligent device mayinclude an RF channel detector that detects the RF channels in use and aDSP that receives the RF channel in use information from the RF channeldetector, and that receives traffic data from a traffic sensor. The DSPuses the RF channel-in-use information to select the RF carrier, and, ifdesired, the RF carrier channel width, and, if desired, the RF guardbandwidth, for the incoming signal, and uses the traffic data to select atleast one of at least one modulator to condition each incoming signal.Additionally, the remote send intelligent device may include wirelesscapability.

An intelligent device system may also be, for example, an intelligentdevice system for local sending and receiving. The intelligent devicesystem for local sending and receiving preferably includes at least oneaddressable device having at least one input and at least one output,wherein at least one of the addressable devices generates an incomingsignal, wherein the incoming signal includes at least a IP signalportion, an intelligent device that generates modulated RF signalcarrying the IP signal portion thereon, and a BUD that receives themodulated RF signal. The intelligent device receives a modulated RFsignal carrying, at least, the digital signal portion thereon from theBUD, and splits the IP signal portion from a non-IP signal portion. Theintelligent device then removes the RF carrier from the IP signalportion and sends the IP signal portion to the input of at least one ofthe addressable devices, and sends the non-IP signal portion to astandard outlet. The intelligent device for local sending and receivingmay additionally include wireless capability.

The present invention is also directed to several methods fortransmitting digital information on a RF carrier through a widebandsignal distribution network. The first method includes providing atleast one addressable device having at least one input and at least oneoutput, sending a signal to a BUD from the output of said at least oneaddressable device, which signal includes at least a IP signal portion,receiving from the BUD at an intelligent device, a modulated RF signalcarrying the, at least, digital signal portion thereon, splitting andfiltering by the intelligent device of the IP signal portion from anon-IP signal portion, removing, by the intelligent device, the RFcarrier from the IP signal portion, sending, by the intelligent device,of the IP signal portion to the input of at least one addressabledevice, and sending, by the intelligent device, of the non-IP signalportion to a standard outlet. A wireless capability may also beincluded.

The present invention is also directed to a second method fortransmitting digital information on an RF carrier through a widebandsignal distribution network. The method includes providing at least oneaddressable device having at least one input and at least one output,generating, by at least one of said addressable devices, of an incomingsignal, wherein the incoming signal includes at least an IP signalportion, generating a RF modulated RF signal carrying the IP signalportion thereon, receiving, at a BUD, the modulated RF signal,receiving, at an intelligent device, of a modulated RF signal carryingthe at least one digital signal portion thereon from the BUD, splittingand filtering, by the intelligent device, of the IP signal portion froma non-IP signal portion, removing, by the intelligent device, of the RFcarrier from the IP signal portion, sending, by the intelligent device,of the IP signal portion to the input of at least one addressabledevice, and sending, by the intelligent device, of the non-IP signalportion to a standard outlet.

The present invention is also directed to a third method fortransmitting digital information on an RF carrier through a widebandsignal distribution network. The method includes generating of anincoming signal, wherein the incoming signal includes at least an IPsignal portion, and generating a modulated RF signal carrying the IPsignal portion thereon.

The present invention solves problems experienced in the prior art,because the present invention provides a network of intelligent devicesthan enable digital video, IP voice/data/video to be modulated anddemodulated onto and off of, preferably, a wideband signal distributionsystem, such as an analog carrier system, and further allows thesplitting off of any analog signal. Further, the intelligent devicenetwork facilitates the use of, for example, the existing EIA/TIA 568standard wiring infrastructure in particular environments, such asoffice buildings, to significantly increase the information throughput,and eliminates the need to rewire a building or add expensiveoptoelectronic equipment to increase throughput on the existinginfrastructure. These and other advantages will be apparent to thoseskilled in the art from the detailed description hereinbelow.

DETAILED DESCRIPTION OF THE INVENTION

It is to be understood that the figures and descriptions of the presentinvention have been simplified to illustrate elements that are relevantfor a clear understanding of the present invention, while eliminating,for purposes of clarity, many other elements found in a typical datadistribution system. Those of ordinary skill in the art will recognizethat other elements are desirable and/or required in order to implementthe present invention. However, because such elements are well known inthe art, and because they do not facilitate a better understanding ofthe present invention, a discussion of such elements is not providedherein.

Digital transmission systems, including digital networks such as directbroadcast satellite, cellular telephone, personal communicationsservice, wireless cable, cellular wireless cable, paging and wirelesslocal loop, often employ analog waveforms, such as RF carrier waveforms,as a physical-layer transport mechanism for the baseband, i.e. theinformation carrying, waveform, as is known in the art. In such aninstance, the baseband waveform is super-imposed on a higher-energywaveform to thereby allow for. travelling of the baseband informationover greater distances than would otherwise be possible with thebaseband information alone.

Historically, cable TV, broadcast TV, analog cellular, analog paging andAM/FM radio, for example, have comprised analog signals that traveled onmodulated RF carriers, which modulated signals have comprised, forexample, signals in the frequency range of 5 MHz to several GHz.Additionally, traditional local analog signals have been carried'ontwisted-pair wires in simple baseband form, without a modulated carrier.

Traditional baseband and multiplexed analog signals are examples ofanalog transmission formats. In the case of traditional baseband ormultiplexed analog communication, analog signals are sent over analogtransmission channels, as is known in the art. Digital carriers, such asT-1 lines, are examples of digital transmission channels for digitalbaseband signals. Digital baseband signals are comprised of digitizedbitstreams, which bitstreams may be formed by a sampling, such as byPCM, of, for example, a voice signal, as is known in the art. In thecase of digital transmission of baseband signals, digital signals aregenerally sent over digital transmission channels. However, both analogand digital signals can be sent using modulation carriers, such as indigital PCS and cellular telephone, DBS (direct broadcast satellite),wireless cable and cellular wireless cable, or hybrid fiber coax, forexample.

PCM is an example of binary coding, a simple coding method to form abaseband digital signal in which one bit, transmitted in one second,requires one Hertz of bandwidth. More complex coding methods, known as“multilevel coding”, such as quadrature amplitude modulation (QAM) orvestigial sideband (VSB), are capable of greater bandwidth efficiencythan PCM. However, the more complex the coding technique, the higher therequirements for signal-to-noise ratio of the transmission channel, and,consequently, complicated techniques such as QAM could not historicallybe carried directly by available analog transmission techniques, such ascategory 5 or higher 568 wiring systems, without exceeding the FCCemission limits and therefore resulting in degradation of the data.Wideband signal distribution systems have addressed the transmission ofanalog data, on a carrier within a specified frequency range, using astandard wiring system such as EIA/TTA 568, with minimal signaldegradation, but have not addressed the transmission of digital data ona carrier on those media.

Following coding, a signal may be modulated, as discussed hereinabove,before it is transmitted. Any single modulation carrier, at any setfrequency, can have 360 different phases, each offset by one degree.Digital modulation systems, such as quadrature amplitude modulation(QAM), take advantage of this to insert digital data at defined pointsas the RF carrier moves through a single oscillation cycle. Digitalinformation can be sent on an RF analog carrier using the presentinvention.

FIG. 1 is a block diagram illustrating a wideband signal distributionsystem 10 used in a display environment 20. The distribution system 10distributes signals within a specified frequency range, such as 5 MHz inexcess of 1 GHz. The system of FIG. 1 can be utilized for distributingany wideband signals, which wideband signals may be any digital oranalog signal, or any RF carrier signal between 5 MHz to in excess of 1GHz, for example. The typical display environment 20 for the widebandsignal distribution network includes a display 22 and a source ofsignals 24, such as a VCR or cable or digital cable TV, which source maybe remotely located.

A twisted pair wire cable 32 is connected to input and output ports of aBUD 38 situated in, for example, wiring closet 40, and carries thereonthe output to the monitor 22 and the input from the source 24. The BUDis discussed further hereinbelow with respect to FIG. 3. As used herein,“BUD” is defined as any type of unit or components for the distributionof wideband signals. The BUD 38 is connected to additional displayenvironments 20 a via the twisted pair wire cables 42, 44 and iscascaded to another distribution unit 46 in a second wiring closet 48 byeither coaxial cables or fiber optic cables 50 connected to thedistribution unit 38 through impedance matching devices 51. It will beunderstood that twisted pair wire cable could be utilized depending uponthe distance between the wiring closets 40, 48. Further, the BUD 38 maybe cascaded to the distribution units 52, 54 within the same wiringcloset 40.

FIG. 2 illustrates a local RF receiver/baseband out intelligent devicesystem 200 for use in receiving digital and analog information on an RFcarrier, which carrier may be, for example, between 5 MHz to in excessof 1 GHz, from a wideband signal distribution system, and for use insending baseband digital information to a wideband signal distributionsystem 10, such as the wideband distribution system of FIG. 1. The localRF receiver/baseband out intelligent device system 200 includes at leastone addressable device 202, and an intelligent device 204 that includesinput 206 and output 208 baluns, and, if necessary, at least one digitalcombiner 212, an RF splitter 214, at least two RF band pass filters 216,218, at least one demodulator 220, a tone detect RF level controlcircuit 226, a DSP 230, an RF Channel detector 239 and a standard outlet232, which, as defined herein, includes, but is not limited to, astandard RF television/computer outlet.

Each intelligent device system 200, 400, 500, 600, 700 and 800 of thepresent invention, in FIGS. 2, 4, 5, 6, 7 and 8 offers the advantagethat a high amount of throughput can be achieved in the transmission ofdigital and/or analog information on an RF, for example, 5 MHz to inexcess of 1 GHz, carrier.

The wideband signal distribution system 10 may allow for distributionof, for example, 29 channels, wherein each channel is 6 MHz in width,and it is known that such channels can handle analog video signals.However, where digital information can be transmitted over the RFchannel, each 6 MHz channel can handle, depending on the modulationtechnique used, in excess of 40 megabits per second of digitalinformation, and new modulation techniques may increase this informationto, and in excess of, 100 megabits per second. This 40 megabits persecond transmission allows for the transmission rate in excess of onegigabit/sec of digital information to be carried on the sum of the 29 RFchannels in the wideband signal distribution system 10. Using advancedmodulation techniques will allow the wideband signal distribution system10 to be expanded up to 60, or more, channels, thereby furtherincreasing throughput data rate.

The wideband signal distribution system 10 functions as a passiveinfrastructure to distribute wideband signals modulated onto RF carrierswithin a specified frequency band among a plurality of outlets 20, whichoutlets may be to and/or from outlets, such as the plurality ofintelligent devices 204, 404, 504, 604, 704 and 804 as used in theintelligent device systems 200, 400, 500, 600, 700 and 800 of FIGS. 2,4, 5, 6, 7 and 8. As used herein, wideband is defined as a signal orsignal sets having an analog or digital characteristic that can bedistributed on a carrier of 5 MHz to in excess of 1 GHz, for example. Awideband signal distribution system 10, as shown in FIG. 1A, preferablyincludes at least one broadband uniform distribution (BUD) unit 38, atleast one modulator and channelizer (MAC) 39, at least one breakout box(BOB) 41, wiring, such as twisted pair or fiber, and coaxial cable, inorder to effectuate connections. Although the wideband signaldistribution system 10 is the preferred transport system for the presentinvention, the embodiment presented herein is exemplary, and the mannerof use of an equivalent component system will be apparent to thoseskilled in the art and is within the scope of the present invention.

A typical BUD unit 38 is illustrated in FIG. 3. Each BUD unit 38, 46,52, 54, such as those shown in FIG. 1, preferably has eight input portsand eight output ports. If there are only eight outlets in the system,then a single distribution unit 38 can accommodate all the outlets.However, for more than eight outlets, at least one more distributionunit cascaded to a distribution unit 38 is required. In this situation,the distribution unit 38 is considered to be a “master” unit and theadditional distribution unit is considered to be a “slave” unit, asdiscussed further hereinbelow. An attribute of the distribution units isthat the units are preferably identical and automatically configurethemselves to operate either in the master mode or in the slave mode.

The distribution unit 38, utilizing twisted pair wire cable, includeseight input ports 62-1, 62-2, 62-3, 62-4, 62-5, 62-6, 62-7, 62-8 andeight output ports 64-1, 64-2, 64-3, 64-4, 64-5, 64-6, 64-7, 64-8. Eachof the ports 62, 64 is adapted for connection to the two wires of arespective twisted pair 66, 68. Additionally, FIG. 3 illustrates themaster/slave switch as having three parts 90, 92, 94, with all of theswitch parts being shown in the “slave” position. The default state ofthe master/slave switch is to its master position, so that the amplifieroutput 80 is coupled through the switch part 90 a transmission path 95including the equalizer 96, which connects the amplifier output 80 tothe splitter input 82, through the switch parts 90, 94. At the sametime, the switch part 92 couples the output of the oscillator circuit 98to the transmission path 95 through the directional coupler 100. Thus,when the distribution unit 38 is operated in the master mode, thesignals appearing at the input ports 62 are combined, looped back,combined with an oscillator signal, and transmitted out all of theoutput ports 64.

Each BUD 38 preferably includes cascade in 102 and cascade out ports,and gain and equalization control 112 to provide proper gain orattenuation of signals within the system. Additionally, the BUDpreferably includes a combiner 72 for applying signals appearing at allof the input ports to the transmission path, and a splitter 84 forapplying signals appearing at the transmission path to all of the outputports. When the BUD is switched to “master state”, it couples thetransmission path to the combiner 72 and the splitter 84. When the BUD38 is switched to “slave state”, it couples the combiner 72 to thesignal outlet instead of to the transmission path and couples thesplitter 84 to the signal inlet instead of to the transmission path.

“Master state” and “slave state” switching may be done automaticallythrough the use of a tone system. When a secondary BUD 38 is added to asystem, it preferably senses a tone produced by the “master” BUD andautomatically switches to “slave state”. In a preferred embodiment, theBUDS 38 are substantially identical and automatically configurethemselves to operate when connected to the system. At least one BUDunit is connected to the intelligent device 204 of the intelligentdevice system 200 of FIG. 2, and each BUD unit 38 of the presentinvention also includes wiring to at least two pin pairs, such as pins3,4 and 7,8, to thereby mirror the pins to and from the addressabledevice 202 of FIG. 2.

Returning now to FIG. 2, the local RF receiver/baseband out intelligentdevice system 200 includes an addressable device 202, preferablyincludes at least two twisted pair of cables 240, or coaxial cables, forexample, which cabling 24Q is shown as connected to pins 3,4 and pins7,8, for example, and which cabling 240 passes to and from theaddressable device 202 to the intelligent device 204 of the intelligentdevice system 200. The addressable device 202 may be, for example, anEthernet card, or a NIC card, in a computer, or may be a display devicethat displays digital information, such as a digital television. Theaddressable device 202 preferably has an address, such as an IP address,assigned thereto, to allow communications directed to that particularaddress to be delivered thereto.

In a preferred embodiment, the twisted cable pair 240 from theaddressable device 202 is preferably passed within the intelligentdevice 204 to at least one balun 206, which balun 206 performs impedancematching, such as to match a balanced twisted pair system 240 to asingle ended system. The balun 206 may be any device known to thoseskilled in the art used to perform impedance matching in RFapplications. The two pair of twisted pair cable may be, for example,unshielded twisted pair cable, or may be devices known in the artcapable of replacing twisted pair cable, such as optical fiber orcoaxial cable.

The intelligent device 204 receives the modulated RF signal, which mayinclude IP and non-IP signal portions thereon, via the RF system input.The intelligent device also receives at least one incoming digitalsignal, such as a digital IP signal, from pins 3,4 of the addressabledevice. The RF system input may be, for example, connected to the atleast one BUD 38, on pins 7,8, as mentioned hereinabove, after the BUD38 has received the incoming digital signal from pins 3,4.

The modulated RF signal, including at least one digital signal, is, uponreceipt at the intelligent device from the BUD 238, preferably splitinto an IP portion of the incoming signal, and into a non-IP portion ofthe signal. The signal entering the intelligent device is preferablysplit by at least one RF splitter 214, and is then differentiatedaccording to the information frequency on the incoming carrier. Forexample, the non-IP portion, digital or analog, of the signal may bepassed through a first band pass filter 216 that passes only the band ofthe RF carrier that includes the non-IP portion, and is preferably thenfed to a standard RF television/computer outlet 232. Only pre-selectedRF channels, as discussed hereinabove, are allowed to pass to thisstandard outlet 232.

These non-IP RF channel signals may pass through a tone detector with anRF level control circuit 226, in order to insure that a high qualitypicture signal is received at the television, monitor, or PC. The tonedetector with RF level control circuit 226 conditions the output RFsignal to the standard RF TV/computer outlet 232 so as to not be over orunder the specifications for high picture quality.

The IP portion of the modulated RF signal is fed through a secondbandpass filter 218 that passes a band outside the band passed by thefirst bandpass filter 216, and the IP portion modulated RF signal isthen demodulated by a demodulator 220. The bandpass filters 216, 218 maybe electronically controlled by the DSP 230. The demodulator 220 stripsthe RF carrier signal from the digital baseband signal, as is known inthe art. Following demodulation, the IP digital signals are combined bya digital combiner 212, such as a multiplexer, if necessary, in order toeffectuate a parallel to serial conversion. The output of the digitalcombiner 212 is a high speed serial digital output. The output of thedigital combiner 230 is routed to at least one addressable device 202via the output cable pair, such as pins 7 and 8, and may be so routedvia a balun 208, if necessary, for impedance matching. The digitalinformation is thereby provided to the addressable device 202.

The DSP 230 (digital signal processor) of FIG. 2 is a DSP 230 as isknown in the art. The DSP 230 preferably controls RF channel detectionand the at least one demodulator 220. Additionally, in a preferredembodiment, the DSP 230 controls the bandpass filters 216, 218.

FIG. 4 illustrates an intelligent device system 400 for the remotesending of digital transmissions using modulated R. The remote send-onlyintelligent device system 400 includes, external to the intelligentdevice 402, a plurality of incoming signals, such as from a desktop unitor desktop video feed, which signal is at least, in part, IP data, butwhich may include non-IP data, a BUD 238, and a remote send intelligentdevice 402 that may include a digital combiner 410, a traffic sensor412, at least one modulator 414, an RF converter section 418, a DSP 420,an RF system channel detector 422, and, if necessary, input/outputbaluns 430 or other impedance matching hardware. The digital signal maybe incoming to an input port of a BUD. This signal may exit, forexample, an output port of a BUD, in a twisted pair output, for example,such as on pins 3 and 4, and may then be passed to the remote sendintelligent device 402.

Upon receipt at the intelligent device 402, the signal may be passedthrough a balun 430, as discussed hereinabove, and is then preferablyfed to a digital combiner 410, ouch as a multiplexer. In a preferredembodiment, each signal fed to the digital combiner 410 may be, forexample, ten megabits per second, and numerous signals from numerousoutput ports of the BUD 238 may be combined as specified according tothe type of digital combiner 410 used. For example, in an embodimentwherein eight ten megabit per second channels enter an 8 waymultiplexer, the signal exiting the digital combiner 410 would exit ateighty megabits per second.

The signal exiting the digital combiner 410 is sent to a modulator bank414 including at least one modulator, and the signal entering themodulator bank 414 is preferably measured via a traffic sensor 412 todetermine if the information volume is greater than the normal capacityof, for example, a single modulator. If the volume is greater, the DSP420 will, in turn, direct the incoming data to as many modulators asnecessary to modulate all data from the combiner 410. The traffic sensor412 may additionally feed information to, or receive information from,the DSP 420, in order to effectuate the decision of the modulators to beused. The DSP 420 is discussed further hereinbelow.

The at least one modulator 414 communicatively connected to the trafficsensor 412 conditions the signal to a modulated digital signal viamethods known to those skilled in the art, such as QAM modulation. Theoutput of the modulator 414 is then modulated to a set carrier channelfrequency by an RF converter section 418, which RF converter section 418may consist of, for example, oscillators, amplifiers, combiners, channelselectors, and channel width adjustors.

The digital signal processor (DSP) 420 is a DSP as is known in the art,and determines the number of modulators, or the channel width or widths,needed to modulate the signal incoming to the traffic sensor 412, aswell as the number of RF channels, and which RF channels, on which theoutput of the modulator or modulators is modulated. Note that, forexample, where QAM modulation is used, QAM modulation is generally 40megabits per second, per 6 MHz RF channel, thus requiring the use of two6 MHz RF channels in order to modulate the 80 megabits per second comingfrom the digital combiner in the exemplary embodiment hereinabove. TheRF channel frequency is selected from at least two available frequencychannels. However, the channel width can, for example, be increased from6 MHz per channel to 12 MHz per channel in order to accommodate, forexample, the 80 megabits per second digital stream, if adjacent channelspace is available or unused.

FIG. 5 is a block diagram illustrating an intelligent device system 500for use in local sending and receiving in the generation of at least onedigital signal on a modulated RF signal. The local send and receiveintelligent device system 500 includes certain of the devices of FIGS. 2and 4.

The system of FIG. 5 preferably includes a plurality of addressabledevices 202, such as Ethernet or NIC cards, or digital display devices,as discussed hereinabove with respect to FIG. 2, which addressabledevices 202 are preferably located at, for example, a desktop location.In a preferred embodiment, wherein twisted pair cable is used, twounused pin pairs, such as pins 1,2 and 7,8, are used to send and receivesignals between the addressable device 202 and the intelligent device502. The plurality of unused twisted pairs, such as pins 1,2 and 7,8 ofeach addressable device 202, are then connected into an intelligentdevice 502, such as the local send and receive intelligent device 502,and may pass within the intelligent device 502 to at least one balun504, for impedance matching.

The signals incoming from each of the addressable devices 202 arecombined by a digital combiner 410, and passed through a traffic sensor412, at least one modulator 414, and an RF converter section 418. Thetraffic sensor 412, at least one modulator 414, and RF converter section418 may be controlled by, or be in communication with, a DSP 420,substantially as discussed hereinabove with respect to FIG. 4.

The output of the RF converter section 418 is preferably impedancematched to a BUD 38, and feeds the signal exiting the RF convertersection 418 to the BUD input port or ports. The BUD output port or portsthen feed an RF splitter 214, which splits the signal entering theintelligent device 502, and the signal is then differentiated accordingto the information frequency on the incoming carrier. The RF splitter214 sends the information of the RF channels in use to the RF systemchannel detector 239. The modulated RF signal is preferablydifferentiated into an IP portion, i.e. a digital data portion, of theincoming signal, and into a non-IP portion of the signal, according tothe information frequency on the incoming carrier. In an embodimentwherein this differentiation is performed by at least two bandpassfilters 216, 218, the bandpass filters may be electronically controlledby the DSP 420.

The non-IP RF channel signals may pass through a tone detector with anRF level control circuit 226, in order to insure that a high qualitypicture signal is received at the television/computer 232. The tonedetector with RF level control circuit situates the output RF signal tothe standard RF television/computer outlet to not be over or under thelimitations for proper picture display.

The IP portion of the modulated RF signal is fed through a secondbandpass filter 218 that passes a band outside the band passed by thefirst bandpass filter 216, and the IP portion is then demodulated by atleast one demodulator 220. The demodulator 220 strips the RF carriersignal from the digital baseband signal, as is known in the art.Following demodulation, the digital signals may be combined by a digitalcombiner 212, such as a multiplexer, in order to effectuate a parallelto serial conversion. The output of the digital combiner 212 is a highspeed serial digital output, on the order of, for example, up to, or inexcess of, several Gbit/sec. The output of the digital combiner 212 isthen preferably routed to a splitter, which splitter feeds an outgoingsignal to the input pin pairs, such as pins 7 and 8, of at least oneaddressable device 202. The input cable pair to the addressable device202, such as pins 7 and 8, may be routed via a balun, if necessary, forimpedance matching.
